mercially available additives are
suitable for the vehicle. The
vehicle manufacturer recom-
mends using coolant with the
BMW LC-18 specification. Do
not mix additives of different col-
ors. Observe the water - additive
mixture ratio of 50:50. Informa-
tion about suitable additives is
available from your Toyota
dealer.
Depending on the motorization,
there are up to two coolant res-
ervoirs in the engine compart-
ment. Check and top up the
coolant levels on a regular
basis.The coolant may be overfilled in
the coolant reservoir when the
vehicle is delivered from the fac-
tory. The normal coolant level is
achieved by operating the vehi-
cle for a longer period.
The coolant level is indicated
using the maximum mark in the
filler neck of the coolant reser-
voir.
Additional information:
For an overview, refer to page

Let the engine cool.
2 Open the hood, refer to page
299.
3 Turn the lid of the coolant
reservoir slightly counter-
clockwise to allow any
excess pressure to dissi-
pate, then open it.
4 Open the coolant reservoir
lid.
5 The coolant level is correct
when it is just below the max-
imum mark in the filler neck.
Safety information
WARNING
With the engine hot and the cool-
ing system open, coolant can
escape and lead to scalding.
There is a risk of injury. Only open
the cooling system with the
engine cooled down.
WARNING
Additives are harmful and incor-
rect additives can damage the
engine. There is a risk of injury
and risk of damage to property.
Do not allow additives to come
into contact with skin, eyes or arti-
cles of clothing. Use suitable addi-
tives only.

Keep antifreeze away from igni-
tion sources. Do no t refill operat-
ing materials into different bottles.
Store operating materials out of
reach of children.

mixture ratio is regulated by the
U.S. EPA and many individual
states; do not exceed the allow-
able washer fluid dilution ratio lim-
its that apply. Follow the usage
instructions on th e washer fluid
container.
WARNING
Washer fluid can ignite and catch
fire on contact with hot engine

ment.
The use of undiluted windshield
washer concentrate or alco-
hol-based antifreeze can lead to
incorrect readings at tempera-
tures below +5°F/-15°C.This chapter describes all stan-
dard, country-specific and
optional features offered with
the series. It also describes fea-
tures and functions that are not
necessarily available in your
vehicle, e.g., due to the selected
options or country versions. This

The maintenance system pro-
vides service notifications and
thereby provides support in
maintaining road safety and the
operational reliability of the vehi-
cle.
In some cases, scopes and
intervals of the maintenance
system may vary according to
the country version. Replace-
ment work, spare parts, fuels
and lubricants, and wear materi-
als are calculated separately.
Further information is available
from a Toyota dealer.
NOTICE
Silicon-containing additives in the
washer fluid for the water-repel-
ling effect on the windows can
lead to damage to the washing
system. There is a risk of damage
to property. Do not add sili-
con-containing additives to the
washer fluid.
NOTICE
Mixing different windshield
washer concentrates or antifreeze
can damage the washing system.
There is a risk of damage to prop-
erty. Do not mix
different wind-
shield washer concentrates or
antifreeze. Follow the information
and mixing ratios provided on the
containers.

determines the maintenance
recommendation using sensors
and special algorithms that take
into account the driving condi-
tions of the vehicle.
The system makes it possible to
adapt the amount of mainte-
nance corresponding to your

Information on service notifica-
tions, refer to page 147, can be
displayed on the Control Dis-
play.
Storage periods during which
the vehicle battery was discon-
nected are not taken into
account.
If this occurs, have a Toyota
dealer update the time-depen-
dent maintenance procedures,
such as checking brake fluid
and, if necessary, changing the
engine oil and the microfil-
ter/activated-charcoal filter.Please consult “Owner's War-
ranty Information Booklet” or
“Owner's Manual Supplement”
for additional information on ser-
vice and maintenance work.
The manufacturer of your vehi-
cle recommends that mainte-
nance and repair be performed
by a Toyota dealer. Records of
regular maintenance and repair
work should be retained.
Scheduled maintenance should
be performed at specified inter-
vals according to the mainte-
nance schedule.

before locking the vehicle.
There is an OBD socket on the
driver's side for checking the pri-
mary components in the vehi-
cle's emissions.Safety information
NOTICE
The socket for Onboard Diagno-
sis is an intricate component
intended to be used in conjunction
with specialized equipment to
check the vehicle’s primary emis-
sions system. Improper use of the
socket for Onboard Diagnosis, or
contact with the socket for
Onboard Diagnosis for other than
its intended purpose, can cause
vehicle malfunctions and creates
risks of personal and property
damage. Given the foregoing, the
manufacture of your vehicle
strongly recommends that access
to the socket for Onboard Diagno-
sis be limited to your Toyota
dealer or other persons that have
the specialized
training and
equipment for purposes of prop-
erly utilizing the socket for
Onboard Diagnosis.

• The warning light
lights up:
Emissions are deterio-
rating. Have the vehi-
cle checked as soon
as possible.
• The warning light flashes under certain
circumstances:
This indicates that
there is excessive mis-
firing in the engine.
Reduce the vehicle
speed and have the
system checked imme-
diately; otherwise, seri-
ous engine misfiring
within a brief period
can seriously damage
emission control com-
ponents, in particular
the catalytic converter.

Lights and bulbs make an
essential contribution to vehicle
safety.
All headlights and lights are
made using LED technology.
Some items of equipment use
light-emitting diodes installed behind a cover as a light source.
These light-emitting diodes are
related to conventional lasers
and are officially designated as
Class 1 light-emitting diodes.
The manufacturer of the vehicle
recommends that you let your
Toyota dealer perform the work
in case of a malfunction.
Follow the safety information,
refer to page 312.
Condensation can form on the
inside of the headlight glass in
cool or humid weather. When
driving with the lights switched
on, the condensation evapo-
rates after a short time. The
headlight glass does not need to
be changed.
If despite driving with the head-
lights switched on, increasing
humidity forms, for instance
water droplets in the light, have
the headlights checked.
